The aim of the course is to provide students with essential analytical training focused on the determination of the basic composition of foods. Students work with analytical instruments and equipment to gain practical experience in the application of analytical methods, to learn how to correctly evaluate the obtained data, and to process them into the required format in accordance with applicable legislative requirements.

The course is conducted in small student groups, who work on a specific task under the guidance of a teaching assistant. At the beginning of each task, the assistant verifies the students’ prior knowledge, explains the practical execution of experiments in the laboratory setting, and is available for consultations as needed. Immediately after completing the task, the students’ notes and interim results in their laboratory notebooks are checked, and the final report is reviewed upon submission.
